What create_collision_polygon does on Godot
AI agents use create_collision_polygon to create or update resources in Godot, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Godot environment.
| Parameter | Type | Required | Description |
|---|---|---|---|
name | object | — | Node name |
points | array | Yes | Array of [x, y] points (e.g. [[0,0], [100,0], [100,50], [0,50]]) |
scene_path | string | Yes | Path to .tscn scene file |
parent_path | object | — | Parent node path (usually a StaticBody2D or Area2D) |
Parameters from the server's own tool schema.
Why create_collision_polygon is rated Medium
This tool creates a CollisionPolygon2D node in a Godot project, which is a reversible write operation. It adds data to the scene but does not delete, execute code, or involve financial transactions. Misuse has a low blast radius as it only adds a collision shape node.
From the tool's definition 'Create CollisionPolygon2D' — creates a new node/resource in the Godot scene
Attacks that exploit this kind of access
The rule that runs create_collision_polygon safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Godot, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_collision_polygon, this is the rule to start with:
create_collision_polygon stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Godot, apply this rule, and every create_collision_polygon call is checked against it from then on.
Questions about create_collision_polygon
Create CollisionPolygon2D. It is categorised as a Write tool in the Godot MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
create_collision_polygon accepts 4 parameters: name, points, scene_path, parent_path. Required: points, scene_path. The full parameter table on this page comes from the server's own tool schema.
Register the Godot MCP server in PolicyLayer and add a rule for create_collision_polygon: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Godot. Nothing to install.
create_collision_polygon is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_collision_polygon rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for create_collision_polygon. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
create_collision_polygon is provided by the Godot MCP server (@yanhuifair/godot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
